4. For Bootstrap。X，你可以这样做:

$('#modal').data('bs.modal')._config.backdrop = 'static';
$('#modal').data('bs.modal')._config.keyboard = false;

如果你不知道模式是否已经打开或者还没有打开，你需要配置模式选项，还有一个选项:

引导3.4

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal').options.keyboard = keyboard;
    $modal.data('bs.modal').options.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

引导 4.3+

var $modal = $('#modal');
var keyboard = false; // Prevent to close by ESC
var backdrop = 'static'; // Prevent to close on click outside the modal

if(typeof $modal.data('bs.modal') === 'undefined') { // Modal did not open yet
    $modal.modal({
        keyboard: keyboard,
        backdrop: backdrop
    });
} else { // Modal has already been opened
    $modal.data('bs.modal')._config.keyboard = keyboard;
    $modal.data('bs.modal')._config.backdrop = backdrop;

    if(keyboard === false) { 
        $modal.off('keydown.dismiss.bs.modal'); // Disable ESC
    } else { // 
        $modal.data('bs.modal').escape(); // Resets ESC
    }
}

将选项更改为_config

你可以使用

$.fn.modal.prototype.constructor.Constructor.DEFAULTS.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.keyboard =  false;

更改默认行为。

你可以像这样使用一个属性:data- background ="static"或者使用javascript:

$('#myModal').modal({
    backdrop: 'static',
    keyboard: false  // to prevent closing with Esc button (if you want this too)
})

也可以看到这个答案:禁止twitter引导模式窗口关闭

You can Disallow closing of #signUp (This should be the id of the modal) modal when clicking outside of modal.
As well as on ESC button.
jQuery('#signUp').on('shown.bs.modal', function() {
    jQuery(this).data('bs.modal').options.backdrop = 'static';// For outside click of modal.
    jQuery(this).data('bs.modal').options.keyboard = false;// For ESC button.
})

有两种方法禁用自举模型区域之外的点击关闭模式

使用javascript $ (' # myModal ') .modal ({ 背景:“静态”, 键盘:假 })； 在HTML标签中使用data属性 data- background ="static" data-keyboard="false" //把这个属性写在你点击打开模态弹出窗口的按钮里。
